Abstract

Apparatus for producing tubular films, especially multilayer blown films, of two or more layers of the same or different plastics material, said apparatus embodying two or more screw extruders mounted on a turntable and die with at least two concentric, juxtaposed annular nozzles substantially coaxial with the axis of rotation of the turntable. Also, improved extrusion dies for production of multilayer tubes or films wherein the feed lines or passages for the plastic composition to be extruded terminate at points situated one behind the other in the axial center portion of the die. The plastic composition is fed through a plurality of radially connecting lines from said points to annular passages and ultimately to annular nozzle means in the die.
